We present a model to show that heat propagation away from a local source depends strongly on dimensionality, leading to dramatic localization in low-dimensional systems. An example of such a system is a carbon nanotube array. We further show that this localization is amplified due to a runaway mechanism if thermal conductivity declines rapidly wit...

The bulk appearance of arrays of vertically aligned carbon nanotubes (VACNT arrays or CNT forests) is dark as they absorb most of the incident light. In this paper, two post-processing techniques have been described where the CNT forest can be patterned by selective bending of the tips of the nanotubes using a rigid cylindrical tool. A tungsten too...
Vertically aligned carbon nanotubes (VACNTs) have drawn significant attention by the researchers because of their nanometric size and favourable material properties. Patterning of CNT forests in the micrometric domain is very important for their application in the area of microelectromechanical system (MEMS). For the first time this paper reports,...
A new type of carbon nanotube, based on the graphenylene motif, is investigated using density functional and tight-binding methods. Analogous to conventional graphene-based nanotubes, a two-dimensional graphenylene sheet can be rolled into a seamless cylinder in armchair, zigzag, or chiral orientations. The resulting nanotube can be described using...
Thermionic conversion involves the direct conversion of heat, including light-induced heat, from a heat source, e.g., solar energy, to electricity. Although the concept is almost a hundred years old, the progress of thermionic convertors has been limited by issues such as the space-charge effect and availability of materials with desirable mechanic...
We propose a method to calculate the output current-voltage characteristics of a light induced thermionic emission device. This approach improves on the existing methods by having both a higher precision and higher range in evaluating the associated integrals, resulting in simulated device characteristics with a wider range of parameters. This meth...
The term solar cell usually brings photovoltaics to mind. Indeed, the direct conversion of sunlight to electricity has dominated the realm of solar-energy harvesting for the past 50 years. However, researchers have now begun to re-evaluate the possibilities of thermionic and thermoelectric energy conversion because of some of their attractive featu...
